Ripley Harbor is a binary star system located in the middle of the Centaurus Reach, composed of a main F0 VI and K9 VA. While several of the planets are very hot, Venus-like scorchers, the system contains an Earth-like and a total of six water worlds, two orbiting the class F, and four around the class K.

The class F has a stormy super-Earth at 7646km radius and 2.1 masses. It has a comfortable 297 kelvin average temperature, a very favourable atmospheric composition at 0.75atm, but a high 1,53g gravity.

The K-class star's water worlds are at a fair temperature and comfortably low gravity, but suffer from low atmosphere density and dangerous dioxides, necessitating respiration gear and skin protection at the surface. Underwater habitation may be highly suitable.

The ninth, earth-sized planet around the class K has a very unusual axial tilt at 89 degrees, causing the icy poles to be pointed directly at the sun for large amounts of time in its orbit. While this planet has a healthy nitrogen-oxygen composition and solid 1.21 gravity, it suffers from a cold 222 kelvin average temperature, a presence of carbon dioxide, and somewhat dense atmosphere, at 2.02 atm. This planet could likely be inhabited, but the low and wildly varying temperature, poisonous atmosphere and extremely long days would strongly test its first explorers.

The system's gas giant with icy moons has not been explored by its discoverer, however the gas giant displays very high oblateness.
